Application filed March 5, 1906. Serial No. 304.419.

pending before the French office) of whichl the following is a specification.

The present invention relates to a portable apparatus for generating acetylene, enabling various im rovements pertaining to apparatus of this ind to be carried into effect.

The drawing accompanying the present de-` scription represents a longitudinal sectional elevation of this apparatus, which comprisesV the following elements:

1 is a vessel in which the carbid of calev by ai domed lid or cover 5, which can be rendered air-tight by means of a rubber ring 2, in. serted in an appropriate recess or groove 4,1

cium is placed. It is closed at top into which enters a projecting rim or fiange 3, formed on the periphery of the Said lid or cover 5, and on the edge of which recess there may be placed a grid or perforated plate 7, the use of whichwill be hereinafter explained. At top andwithin the domed lid or cover 5isa tapped socket 6,into which is screwed a pipe 8, up which ,the water rises, and which pipe passes through the bottom of the vessel 1 and through a suitable socket 11. This tube is provided with a small lateral orifice 9 and terminates at its lower end in a block 10, forming a stopper and abutting against the bottom of the vessel 1, and which by means of a leather or rubber washer 12, interposed between it and the bottom of said vessel 1, constitutes a tight joint. This stopper is provided with a central passage 13,by means of which the interior of this latter is placed in communication with the surrounding space and presents a truncated seat 14, the purpose of which is hereinafter explained. The socket 11 is screwthreaded externally and carries.by means of a tapped ferrule, a perforated tube 15, which is arranged concentrically with the tube 8 and is provided at its upper end with lugs 16, whereby its screwing' into place is facilitated. Within this tube 15 is an imperforate tube 16, shorter than the tube 15 and provided at its upper end with a flange 17, by means of which 1t is supportedl in place.

Above the vessel 1 is a closed space 18, constituting a compression-chamber, the working of which will be hereinafter described. This chamber is supported on the one hand by a tubular stem 19, forming `an extension of the tube 8, and on the other hand by the tubes 20 and 41, both of which serve for the escape of the gas generated in the vessely 1. The tubular Stem 19 is screw-threaded near its upper end and serves more particularly for the purpose of guiding the rod' 21,(screwed at 22,) which carries at its upper end a milled button or knob 23 and at its lower end a cylindroconical enlargement 2 4, which by being applied to or removed from the seat 14 mits the passage 13 to be closed or opene as desired. The tube 20, through which the gas to be used for lighting purposes esca es, is

closed at its lower end by a screwed p ug or stopper 25 through which passes a Siphonpipe 26 to permit water carried over by the gas to drain off and to collect at the bottom of the tube 20. Said water will be removed when required by removing the plug 25. The chamber 18 likewise carriesv a bent pipe 27, provided with a boss or ferrule 28 to receive a rubber tube and witlia cock 29. This pipe 27 is in direct communication with the tube 20. The chamber 18 is furthermore furnished with a tubular extension 30, in which is a valve 32, kept on its seat by a spring 33 of suitable strength. In the top of the tubular extension is an orifice 31. On they chamber 18, but traversing it without communicating with it, is another tube 34, which terminates at its upper end in a funnelshaped mouth 35 and closed by a screw-stopper 36, having an orifice 37.

The e'ntire arrangement or system thus described is located in a closed receptacle or vessel 38 of any suitable form, in which it is supported by hooks or latches 39, held in position by tightening-bolts 40.

The working of the apparatus -is as follows: After the vessel 1 has been charged with carbid of calcium up to a suitable point the cover or lid is applied, thus forming a tight joint by means of the rubber ring 2. Then the block 10 is turned,so screwing the tube 8 'into the Socket 6 and tightening the ring 2 and effecting the closure. The plug or valve 24 is then'applied to its seat by operating the milled button23, and when this is done the whole is inserted in the vessel or receptacle 38, in which a predetermined, quantity of water has previously been placed and.

to which more may be added, if necessary,-

through the tube 34. The whole is then fixed IOO IOS

IIO

in place bymeans of the latches 39, and the apparatus is ready for working. If now the cock 29 and the valve 24 be Opened, the water in the vessel 3S will pass through the orifice 9 into the vessel 1, wherein it will act on the carbid, so producing acetylene, which latter will drive out the air coniined in the apparatus and take its place. From this moment there is a regular production of gas. Ii it be de sired to discontinue it, the cock 29 must be closed. The acetylene gas continuing to generate increases the pressure in the vessel 1, and consequently the expulsion of the Water is effected through the orifice 9 and the passage 1,3 into the vessel 38. By closing the plugor valve 24 the water is prevented from returning to the carbid. The grid or perforated plate 7 serves to prevent the carrying over of the carbid, which would detrimen tally obstruct the tube 26. In case the tap 29 should have been closed and it has been forgotten to close the plug or valve 24;, by operating the milled knob 23 the expulsion of the liquid will take place through the orice 9 and the passage 13, as previously stated, after which'if the action of the water on the carbid continues, for there is always a little waterlat the bottom of the vessel 1, the gas whichl will continue to generate will ilow through the tube 41 and will collect in the chamber 18, where it will be able to attain a pressure determined by the spring 33, after which it will escape through the orifice 31 into the atmosphere. In cases where under the'same conditions any gas should escape through the orifice 9 and the passage 13 this gas will expand in the water in the vessel 33 and will escape into the atmosphere through the oriice37 in the plug 36, thus preventing any undue pressure in the vessel 38.

Having now described my invention, what I claim, and desire to secure by Letters lat ent, is

A portable apparatus for generating acetylene, said apparatus including the following elements: an external receptacle for the Water, provided with a removable cover; an inner receptacle for the carbid of calcium, closed by means of an air-tight cover a central passage at the bottom of the inner receptacle 5 an adjustable plug for closing or opening said passage, a central tube above said passage, provided with a lateral opening for the water coming from the external into the internal receptacle; a siphon arrangement on the cover of the inner receptacle acting as a eonveyer from the gas-generator to the drier; a tube receiving said arrangement, and communicating with the apparatus to be fed. with gas an external tube insuring said communication and provided with a tap for arresting or permitting said exit; a protecting perforated plate for preventing the carrying over of the carbid or the lime; a compressionchamber at the top of `the external receptacle; a tube joining said chamber with the top of the inner receptacle, and provided with a safety-valve established on the cover of tbe external receptacle.

In testimony whereof I have signed my name to this specification in the presence of' two subscribing witnesses.
